What is the minimum width of aisles in places of assembly serving 60 seats or more?

In places of assembly that are designed to accommodate 60 seats or more, the minimum width of aisles is established to ensure safe and efficient movement of patrons, particularly in emergency situations. The choice of 1.22 meters as the minimum aisle width aligns with standard building code requirements that prioritize accessibility and egress. This width allows for comfortable passage when people need to enter or exit quickly, such as during an evacuation.

Moreover, the code specifies that aisles must be wide enough to accommodate not only the average patron but also to facilitate the movement of any emergency personnel and equipment if necessary. Aisle dimensions are carefully regulated based on the type of assembly occupancy to ensure safety and compliance with local and national building codes.

In contrast, options that provide greater widths may apply to specific use cases or designs but are not the minimum requirement for general assembly areas. Thus, while those may serve different purposes, they exceed the basic regulatory standards.
